Soap stock is a by-product of soap, resin acids and wax materials that are separated as a result of washing and neutralization of free fatty acids with caustic and in the refining of vegetable raw oil. It contains water and a low amount of oil. It is obtained during the elimination of free fatty acids (alkaline refining) by caustic soda neutralization of raw oils. It is a mixture of fatty acid soaps, salts, phospholipids, impurities and entrained neutral oil.  Soap Stock Splitting is done with Sulphuric /  Hydrochloric acid to obtain Acid oil.

As a result of the usage of acid, soap stock splitting process is a highly corrosive process. Designed under technical expertise of Mr Ashok Jain (Promoter of M/S Plasto-Fibre Ind), we offer a very specialized leak proof & corrosion-proof Soap Stock Splitting Plant / Acid oil plant. First Soap Stock Splitting / Acid Oil Plant we ever manufacture in fibreglass was way back in 1990.

With over 25 years of experience in designing, manufacturing & commissioning of over 200 Soap Stock Splitting plants / Acid oil plants for all sizes of refineries & our plants have over 95% efficiency with reduced acid consumption, low quantity of sludge & fumes, lower acidity of effluent & high quantity of acid oil with enhanced quality.  Our Soap Stock Splitting Plants / Acid Oil Plants contain specially designed corrosion-free pipelines, pumps, valves etc.
